And latency is disproportionately important when you're concerned only with
HTTP performance.

However, pings *can* be used to measure bandwidth, by sending multiple
sizes of ping and measuring the difference in response times between small
and large pings.  On a graph of ping size vs. response time, you'd see the
y-intercept representing base latency and the slope representing bandwidth.
This is how bing does its work.
